docker容器镜像拉取失败解决方案

adele@ubuntu:~$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).
See 'docker run --help'.

解决方案：

sudo vim /etc/docker/daemon.json

 插入镜像源

{
        "registry-mirrors":["https://docker.registry.cyou",
        "https://docker-cf.registry.cyou",
        "https://dockercf.jsdelivr.fyi",
        "https://docker.jsdelivr.fyi",
        "https://dockertest.jsdelivr.fyi",
        "https://mirror.aliyuncs.com",
        "https://dockerproxy.com",
        "https://mirror.baidubce.com"
        "https://docker.m.daocloud.io"
        "https://docker.nju.edu.cn",
        "https://docker.mirrors.sjtug.sjtu.edu.cn"
        "https://docker.mirrors.ustc.edu.cn"
        "https://mirror.iscas.ac.cn"
        "https://docker.rainbond.cc"]
}

查看一下

adele@ubuntu:~$ cat /etc/docker/daemon.json
{
  "registry-mirrors": [
    "https://docker.registry.cyou",
    "https://docker-cf.registry.cyou",
    "https://dockercf.jsdelivr.fyi",
    "https://docker.jsdelivr.fyi",
    "https://dockertest.jsdelivr.fyi",
    "https://mirror.aliyuncs.com",
    "https://dockerproxy.com",
    "https://mirror.baidubce.com",
    "https://docker.m.daocloud.io",
    "https://docker.nju.edu.cn",
    "https://docker.mirrors.sjtug.sjtu.edu.cn",
    "https://docker.mirrors.ustc.edu.cn",
    "https://mirror.iscas.ac.cn",
    "https://docker.rainbond.cc"
  ]
}

成功。然后重启

sudo systemctl daemon-reload
sudo systemctl restart docker
systemctl status docker

adele@ubuntu:~$ sudo systemctl daemon-reload
adele@ubuntu:~$ sudo systemctl restart docker
adele@ubuntu:~$ systemctl status docker
